GHK-Cu (Glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper complex first identified in human plasma. It functions as both a signal peptide (instructing cells to repair) and a carrier peptide (transporting copper into cells).

Research and clinical data highlight its benefits across four primary categories: Dermatology, Trichology (Hair), Wound Healing, and Systemic/Gene Modulation.

Dermatology & Anti-Aging

GHK-Cu is most widely documented for its ability to remodel skin tissue. Clinical trials comparing it to industry standards like Vitamin C and Retinoic Acid have shown superior results in collagen stimulation.

Hair Growth & Scalp Health

GHK-Cu is often used as an alternative or adjunct to Minoxidil due to its ability to enlarge hair follicles and extend the growth phase.

• Follicle Stimulation: It inhibits 5α-reductase, the enzyme responsible for converting testosterone into DHT (the primary cause of male pattern baldness).
• Vascular Support: Promotes angiogenesis (new blood vessel formation) via the VEGF pathway, ensuring follicles receive adequate oxygen and nutrients.
• Clinical Efficacy: Some studies suggest it performs comparably to 5% Minoxidil in improving hair density and shaft strength without the common irritation associated with chemical treatments.

Wound Healing & Tissue Repair

The peptide was originally discovered for its role in the body’s natural response to injury.

• Acceleration: Research indicates a 40-50% acceleration in wound closure compared to controls.
• Anti-Inflammatory: It suppresses pro-inflammatory cytokines like TNF-α and IL-6, while increasing antioxidant enzymes like Superoxide Dismutase (SOD).
• Surgical Recovery: Used post-procedure (microneedling, laser, or surgery) to reduce scar formation and improve the structural quality of regenerated tissue.

Systemic & Gene Modulation

One of the most remarkable findings regarding GHK-Cu is its influence on the human genome.

• DNA “Reset”: According to research (notably by Dr. Loren Pickart), GHK-Cu can up- or down-regulate over 4,000 human genes, essentially shifting gene expression toward a younger, healthier state.
• Anti-Cancer Potential: In studies using the Connectivity Map (Broad Institute), GHK-Cu was one of only two compounds found to reverse the gene expression of metastatic colon cancer, potentially suppressing “metastatic” genes.
• COPD & Lung Repair: It has been shown to restore function in lung fibroblasts from COPD patients and may reverse gene expression changes associated with emphysema.
